Lucent Technologies Inc.
Applications
Line Termination
For the following applications (shown in Figures 12—15), the Lucent 2741 and 2745 Series transformers are rec-
ommended. The same transformers used for the T7290 device can be used for the T7290A device. The tolerance
of all transformer turns ratios is a maximum of
±
2%. The tolerance of all resistors in the transmit path (excluding the
cable termination) is a maximum of
±
1%.
